TOY AEROPLAN E.

Application filed June, 18.

The present invention relates to improve,

ments in toy aeroplanes of the type utilizing rubber bands for thepropelling power, and the toy constructed according to my invention isdesigned for a flight of sufiicient distance to insure thenovelty andattractiveness of the toy. Means are provided whereby the toy device maybe propelled, as a vehicle, along the floor or other hard surface, andin addition floats maybe attached and substi an driven as an auxiliarymeans to the propeller.

1 The invention consistsin certain novel com- I binations andarrangements of parts as Wlll hereinafter beimore fully pointed out andclaimed. In the accompanying drawings I have illustrated one completeexample of the physical embodiment of my invention wherein I haveillustrated also wheel sub- H stitutes that may alternatelybe used Withthe toy, in which the parts are comblned and arranged according to onemode I have thus far devised for the practical application of.

the principles of my invention.

Figure 1 is a top plan view of the toy of my invention equipped as awheeled-vehicle.

Figure 2 is a view in side elevation of the toy of Figure 1.

Figure 3 is a sectlonal View at line 83 of Figure 2.

Figure 4 is a sectional vlew at hne 4t4: of Figure 2.

Figure 5 is a detail view of a float used as a wheel substitute at thefront of the toy and Figure 6 is a view of a float used as a wheelsubstitute at the rear of the toy, these floats being employed when thetoy is used on the surface of water.

Figures 7 and 8 are side views of the front and rear runners used aswheel substitutes when the toy is used on a snow or ice surface.

In carrying out my invention I use a body or board 1 at the front end ofwhich 1s the air propeller 2 fixed to revolve with the propeller shaft 3that is provlded with a fly or balance wheel 4 and the shaft isjournaled 1927. Serial No. 199,829.

in hearings in the walls of a gear box5 secured at the front of theboard and on its top surface, the shaft of course being located in thelongitudinal center of the boardand extending longitudinally thereof.

\(Vithin the b0 5 the propeller shaft is provid'ed with a pinion 6 withwhich a pair of gears 7, and 8 mesh, the gears being fixed to revolvewith the spaced, longitudinally ex: tending driven shafts 9 and 10locatedparallel with. and atthe sides of the propeller shaft 3 and journaled also in the walls of the gear housing, or box 5. This train'ofgears,

extends transversely of the body, of the toy and forms the propelling orpropulsion mechanism for the propeller, and the train of gears may beretained against operation, by means of a pawl 11 pivoted at 12 andprovided with a counterweight or handle 12, asfor instance when thepower is being developed by twisting or winding two rubber bands 14 and1:) thatare suspended at opposite sides of the longitudinal center ofthe body of the toy.

These endless elastic bands, at their front ends are suspended byhooks16 from the rear ends of the driven shafts 9 and 10, and at their rearends aresuspended from hooks 17 on the front ends of a pair of powershafts 18 and 19. The power shafts aredisposed at the sides of thelongitudinal center of the toy and j ournaled in bearings in the wallsof the rear gear casing 20,and of course the power shafts are alinedwith their complementary driven shafts at the front of the toy. On thepower shafts are pinions 21 and 22 and between these pinions is locatedthe large gearwheel 23 on the power shaft or crank shaft 24 which isalso journaled in bearings in the wall of the rear gear housing andprovided at its rear end with a projecting hand crank 25. The power gearis provided with a pivoted dog or detent 26 which is shown in lockedposition in Figure 1 to prevent movement of the power shafts and crankshaft, as during the time the toy is being operated. To develop power,the dog 26 is released, and the pawl 11 is locked with gear 8 as shownin Figure 3 in order that by turning the crank 25 the two rubber bandsmay be twisted and thus store power in them.

After the power has been developed, the dog 26 is set as in Figure 1,and if the toy is to be propelled, the'pawl 11 is released, whereuponthe untwisting or turning movement of shaft, a belt 28 passing around apulley 30 and the axle 31 on which the pulley and traction wheels 33 arefixed. The belt passes through a hole 29 in the board 1 and transmitspower from the propeller shaft to the axle, and thence to the tractionWheels 33, whose tractive power assist in the propulsion of the toy overthe floor or ground surface. The front axle is ournaled in an underframe or wheel frame 32 of U-shape that is secured at the under side ofthe board anda pair of diagonal braces 34 are connected at their lowerends to a cross rod 34 fixed in the U- frame, while the upper ends ofthese braces pass through holes in the board and are threaded toaccommodate lock nuts 35. The lock nuts are turned tight against the topsurface of the board and hold the braces I through a hole in the boardto accommodate the wing nut 39, and the latter is used to clamp thebracket in adjusted position to properly locate the steering wheel;

In Figure 5 a substitute for the front wheels is shown as a floatsupported by the float-frame 41 from the wheel frame 32, and in Figure 6the float 42 and frame 43' are used craft and propelled by theairpropeller 2.

' In Figure? one or more runners 45 are attached at 46 to the wheelframe 32, and in FigureS one or more runners 47 are attached by frames48 and bolts 44 at the rear of the toy as wheel substitutes, thusadapting the toy for use on ice or snow over which it is propelled bythe air propeller.

These wheel substitutes form parts of the toy and are readilyinterchangeable with the wheels and with each other and add interest Qgears for the pinion, of a crank shaft having a gear thereon, a pair ofpower shafts having pinionsmeshing with thegear, and a pair of endlessrubber bands suspended between the respective driving and power shafts.

2. The combination in a wheeled toy with a propeller shaft having apinion and a pivoted pawl for engagement therewith,a pair of spaceddriving shafts, and driving gears on the latter shafts meshingwith thepinion, of a" pair of traction wheels and their axle, powertransmissionmeans between the propeller shaft'and axle, a crankshaft andgear thereon at the rear of the toy,'a pair of power shafts havingpinions engaging said gear,'and a pairof endless rubber bands suspendedbetween the respective driving and power shafts, and a pivoted detentfor coaction with thecrank gear.

In testimony whereof affix'my signature.

WILLIAM H. DANIEL.
